Jet® septic aerators will be red and Norweco Singulair® aerators will be blue. Measure your tank opening to determine which aerobic septic system pump replacement to buy or call our Customer Service at (800) 778-1540 for assistance.
Every Flagg-Air® septic aerator includes a separate 7-amp mini circuit breaker to protect the motor. Installation of this mini breaker is required for warranty purposes. If you are replacing a Flagg-Air® septic shaft aerator, it is recommended to replace an existing 7-amp breaker with the new one that was shipped with your unit.
